Gone in about 2 hours
A model named "Dubi-mega" appeared on Oct. 27 (the morning of Oct. 28 Japan time) on "Arena," a site that compares AI models by pitting them against each other anonymously, and disappeared after about 2 hours. @aitrackerbot, an X account that tracks model appearances, reported it.
Companies sometimes put unreleased models on Arena anonymously to gather user ratings.
Close to DeepSeek's lineage but unconfirmed
@aitrackerbot examined the model with a system that estimates the developer from the habits of a model's output. Its degree of match with the lineage of China's DeepSeek was 0.796, just short of the 0.800 threshold for confirmation. Its habit of building out pages more elaborately than requested resembles models such as Qwen from China's Alibaba, DeepSeek and MiMo from Xiaomi (小米), the account said.
There are rumors that DeepSeek will release a large model at the end of the year, and on Nov. 1 the name of its higher-end model "V4.1 Pro" was found in evaluation settings. However, nothing links Dubi-mega to these, and the developer is unknown.
